UNDERSTANDING THE 40% REFF ADVERTISED BY KOL CORRECTLY
Scrolling through the web, I see many KOLs advertising a lifetime cash rebate of 40% on transaction fees, which is not true, folks. Binance only allows setting a maximum cash rebate of 20% on lifetime trading fees when registering through Reff. You need to buy some BNB and enable the feature to use BNB for transaction fees to get an additional 25% off (20%x25% means you save 40%). However, this part will be lost if your BNB balance is insufficient to cover the transaction fees.
